Be it known thatI l'. ("iinis'r. W. TiiiPPEN- siii-3,. a citizen of the United Sintes. residing at'Jfl'ersoii City, in the countyof (lole and State of Missourihure invented new and iisefiil Improvements in Piston Rings, of which the following is :i specification.

This invention relates tir-packing rings for use in engines, puiiips ci" various kind.

' of A compression from and in fact all devices in which piston rings are. necessary, and has for its object the provision of a piston ring formed of two similz'ir sections which are supciposed and which are provided with means whereby relative rotation of the' ring sections isprevented. the advantage beingr thatthe sections will always lap joints so as to prevent leakge or oil into the explo- Sion clitiinlier;l this of. course improving the running of the engine generally :is well as preventing fouling of the spark plugs.

An important and more specific object is the provision of :i two-piece ring of this character in which each section carries :nlug disposed betweenV the ends of the other section. czech lughailing inclined sides and the adjacent ends of the other section being likewise inclined.

Another object is the provision of :i ring of this character which is .so constructed that the pressure or tension thereofwill be evt-nl distributed throughout the entire circuin ronge so that. uniiorni wear will be iiisured which will prevent the cylinders from being worn into :in oviil or elliptical cross Section :is so often occurs in the use of the ordinary ring.

An additional object: is the provision of a ring which willi be, simple and inexpensive in iiianufncture. highly eflicierit'in use, diii'nble in service., and a. general improvement in the zi'rt.

lVith the above and other objects and advant-ages in View. t-lie invention consists in the details of construction to hehereina'fter more fully described and Aclziinied'zind illustinted in thil :iccomimnying drawings in which- Figure 1. is :i plan view of my ring assemed, Figure 2 of the lugs,

Referring more particularly to the. drawtwo sections whcli.are identical and each section includes or is formed as a, split ring body 10 which isof uniform which has its greatest 'width at thepointdiametrically opposite 'the split. The ends at the split are inclined, as shown et 11.

Formed integrlly at the widest part of'eaLcli section, that is at the point, diametrically opposite the split, is an integral lug signed to fit. the other section andthis lug has inclined ends 13 adapted to conformingly engage,y or at leist" substantially engage, ends of the split. f In the' use of the ring -the superposed with-,the lu within the splitof the ot assembled ring is ordinary manner. in th e same manner 'as an other ring but will be far more eicient in operation and service as the assembled rings'are of''uni-` form diameter and thickness ns ,well as cnqss sectional congumtion The disposition of the lugs within theV lits;of course' prevents releti've rotation off e sections'nd thereby positively eliminates any danger. of the splits yof each 'disposed' er; lifter Vwhich 'tlie` .pllced position in the own my ring a's formed of thickness but 12 debetween theends at thosplit of 7| the inclined Lisectons are-.

will not depart from fthe' spirit ofthe inv 'tion or the scope of the xsub'joined claims.' Having thus described my invention, I
